Inclusion-exclusion principle proof

WebOct 12, 2015 · In lieu of a rigorous proof, it is easy to see that the IEP rests on the following principle: suppose that $x$ is a member of $n$ sets. Then $x$ gets counted $n$ times on the first count, subtracted $n$ choose $2$ times on the second count, added back in $n$ choose $3$ times on the third count, etc. In other words: WebTheInclusion-Exclusion Principle 1.

WebThe proof of the probability principle also follows from the indicator function identity. Take the expectation, and use the fact that the expectation of the indicator function 1A is the probability P(A). Sometimes the Inclusion-Exclusion Principle is written in a different form.
